110. number of protons = mass number - neutrons = 271 - 261 = 110
The atomic number is the number of protons in the nucleus of an atom of any given element. The mass number is the number of protons and neutrons in the nucleus of an atom of an isotope of an element.
No, atomic number equals the number of protons.The number of neutrons is NOT specific to an element, and various atoms of the same element can have different numbers of neutrons - these are called isotopes.
it shows how many protons are present in an atom
Its atomic number. In other words the number of positive protons in the nucleus of each atom and the number of negative electrons surrounding the nucleus of each atom.
The mass number is the total number of protons plus neutrons in the nucleus. The atomic number is the total number of protons in the nucleus. So subtract the atomic number from the mass number and that will give you the total number of neutrons in the nucleus.
You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.
Atomic weight of an element is the number of protons plus neutrons in the nucleus, atomic number is the number of protons only.
The atomic mass in an element is the total number of protons and neutrons in an atom's nucleus.
The atomic number of an element is determined by the number of protons in its nucleus.
The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons)
Atomic mass= Atomic no. + no. of neutrons So when the atomic no. is subtracted from the atomic mass, the result would be equal to the number of neutrons present in the nucleus of the atom of the element.
The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.
An Element's behavior depends PRIMARILY upon the Number of Protons in the Element's [atomic] Nucleus and secondarily upon the number of Neutrons that are included [with the occasional variation] in the Atomic Nucleus.
The mass number is the sum of neutrons and protons in an atomic nucleus.
12. the atomic number of an element is the number of protons in it's nucleus. The mass number is the number of protons+neutrons. Therefore the element has (32-20)12 protons.
The atomic number is the number of protons in the nucleus of an atom of any given element. The mass number is the number of protons and neutrons in the nucleus of an atom of an isotope of an element.
No.The cloud of electrons surround the atomic nucleus and, for each individual element, there are a different number of electrons in the cloud. This number of electrons is matched by the samenumber of protons in the atomic nucleus.However, the atomic nucleus also contains neutrons, and there is a variable number of neutrons in the nucleus. It is this variation in the number of neutrons that makes the isotopes of an element.
